Drosera sect. Stolonifera is a section of ten tuberous perennial species in the genus Drosera that are endemic to south-west Western Australia. The species all have a similar growth habit and all have fan-shaped leaves, but the morphological differences and lack of natural hybrids support the division of the D. stolonifera species complex.
The first species in the section was discovered by Charles von Hügel in the Swan River region in 1833. D. stolonifera was formally described by Stephan Endlicher in 1837. Johann Georg Christian Lehmann followed that with two more species in 1844: D. ramellosa and D. porrecta. In 1848, Jules Émile Planchon organized these three species under section Ergaleium series Erythrorhizae subseries Stoloniferae (initially spelled Stolmiferae). Planchon also added the species D. humilis and D. penduliflora (later reduced to synonymy under D. ramellosa) to the new subseries. D. platypoda was added in 1854 by Nicolai Stepanovitch Turczaninow and D. purpurascens, described by August Friedrich Schlotthauber followed in 1856. In 1864, George Bentham reorganized the species under section Ergaleium, recognized fewer taxa, and suggested the reclassification of D. humilis as a variety of D. stolonifera. In 1906, Ludwig Diels took Bentham's suggestion and reduced D. humilis to the variety rank. In Diels' monograph of the family, he reorganized the species in this section into subgenus Ergaleium section Erythrorhiza.
